All of these features contribute towards enhanced driving dynamics and an exceptionally sporty, aggressive, and powerful appearance. Alcantara Sports seats specifically developed for the M Sports Package, an inter alia, M leather-clad steering wheel, M gear lever knob, M footrest, an anthracite BMW Individual roof lining and M aluminum hexagon interior trim strips comprise the elegant interior if this vehicle.
